Jesse Metcalfe Talks Dallas Season 2 Finale Mysteries

They mystery of where Pamela Barnes Ewing is in the world (or if she’s even still alive) will continue on Monday’s Season 2 finale of TNT’s “Dallas” – but could that have a connection to the mystery of who killed J.R. Ewing?

Jesse Metcalfe hinted there could be a link on Thursday’s Access Hollywood Live.

“A lot unfolds as part of J.R.’s master plan” Jesse, who stars as Christopher Ewing (Bobby’s son) on the show, told co-hosts Billy Bush and Kit Hoover. “It’s all kind of surrounding his murder, and part of that mystery is possibly finding my mother and getting her shares of Barnes Global so we can possibly take over that company.”

J.R., who was played by the late Larry Hagman, was searching for Christopher’s mother when he was killed in Mexico. He had previously tried to track her down in Abu Dhabi, but the mystery of where Pam is – for now – is still unsolved.

As fans of the show know, Christopher got a call from a bank in Switzerland about a woman believed to be his mother, and Bobby’s son exited the episode on the way to see if the woman in the hat and sunglasses really is her.

“Christopher definitely explores that lead. He takes off to Zurich, Switzerland, to find out if that is in fact his mother,” Jesse said.
